octopus codefresh UPGRADE

Affected: >= 2.0.0 and < 2.11.15

Fixed in: 2.11.15

Safe to downgrade to: a release before 2.0.0

1. Check installed version

apt-cache policy codefresh || rpm -q codefresh || codefresh --version

2. UPGRADE to 2.11.15 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade codefresh

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade codefresh

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 2.0.0 (Debian / Ubuntu)

apt-cache madison codefresh sudo apt install codefresh=<VERSION_BEFORE_2.0.0> sudo apt-mark hold codefresh

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list codefresh sudo dnf downgrade codefresh-<VERSION_BEFORE_2.0.0> sudo dnf versionlock add codefresh

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
